Get substring between substring and first occurrence of another string

Question

I have URL pathnames that look similar to this: /service-area/i-need-this/but-not-this/. The /service-area/ part never changes, and the rest of the path is dynamic.

I need to get the part of the URL saying i-need-this.

Here was my attempt: location.pathname.match(new RegExp('/service-area/' + "(.*)" + '/'));.

The goal was to get everything between /service-area/ and / but it's actually going up to the last occurrence of /, not the first occurrance. So the output from this is actually i-need-this/but-not-this.

I'm not so good with regex, is there a way it can be tweaked to get the desired result?

Your code is helpful to point out what the isuse is with your solution. Can you please post an edit to include it? — Incorporeal Logic

@PaulBeverage I did explain the issue with my solution. My solution gets everything up to the LAST occurrence of /, I need it to go up to the FIRST occurrence of /. — chrispytoes

Regex is overkill for your case. Just split URL by / and get 2nd part. — hindmost

Sorry -- my brain apparently lost it at some point...not sure how I missed that. — Incorporeal Logic

You need a lazy regex rather than a greedy one - so (.*?) instead of (.*). See also: What do 'lazy' and 'greedy' mean in the context of regular expressions?

You can do this without a regex too using replace and split:

var path = '/service-area/i-need-this/but-not-this/';

var res = path.replace('/service-area/', '').split('/')[0];
console.log(res);
